Question

1. a water-walking ball has a volume of approximately 904.32 ft³. what is the radius of the ball? (v = \frac{4}{3}\pi r³)

Explanation:

Step1: Substitute V into the formula

$904.32 = \frac{4}{3}\pi r^3$

Step2: Isolate $r^3$ term

$r^3 = \frac{904.32 \times 3}{4\pi}$

Step3: Calculate $r^3$ value

$r^3 = \frac{2712.96}{12.5664} = 216$

Step4: Solve for r

$r = \sqrt[3]{216}$

Answer:

$6$ ft
